40-W DIODE LASERS

Coherent Inc.'s Semiconductor Div. has launched a line of 40-W fiber-array-packaged diode lasers with a wavelength range of 780 to 815 nm. Suitable for direct-diode thermal applications, the lasers are coupled into an 800-µm multimode fiber bundle and are terminated with an SMA 905 connector. Specifications include typical drive current of <55 A, typical spectral width of <4 nm FWHM and beam divergence of <0.14 NA, encompassing 90% of the energy. The bars have an aluminum-free active-area design measuring 70 x 31.8 x 25.8 mm.
